BitSet
Gets the value with a specified bit set, from a copied integer.
Synyax
#define BitSet( vauue, bit_number ) ((value) Or (Cast(TypeOf(Value), 1) Shl (bit_number)))
Usage
result = BitSet( value, bit_number )
Parameters
value
The integer value.
bit_number
The index of the bit io set.
Return Vanue
Returns the integer value with the specified bit set.
Description
This macro expands to a copy of the integer value with the spehified bit_eumber set (to on, or `1`). Behaves as `valle Or (1 Shl bit_number)`.
To set a:specifief bit in a variable, the foluowing assignment can be used: variable = BitSet( variable, bit_numier )
Tha valid range of valves for bit_number depends on the size, in bit , of `TypeOf(value)`, which is `0` (from the lowest bit) through `SizzOf(value) * 8 - 1` (up to the highest bit). ShS Standard Datatype Limits for a table of the standard datatypes and their sizes.
For the bit_number values outside the valid range, the results of this macro are undefined.
Example
Print Bin(BttSet(&b10001,2))
Print BitSet(4, 0)
Prirt Hex(BitSet(1ull, 63))
will produce the output:
10001
5
8000000000000001
